Let us now draw a rug.

1. Let us now draw a rug. A rug is unlike the door or window drawn in the previous sections because it is drawn on the floor, not the wall. Therefore, to start the rug it is best to draw a horizontal line on the floor that shows the side of the rug closest to you. Remember that the door and window were started with vertical lines on the wall.

2. Drawing a Rug in One-Point Perspective. The orthogonals show where the sides of the rug are. They start at the ends of the horizontal line that is the front of the rug. If we wanted a narrower rug, we should have started with a shorter horizontal line.

3. Drawing a Rug in One-Point Perspective The horizontal line close to the back wall is the end of the rug. You can make a smaller rug by drawing a horizontal line closer to the front of the rug. The lines showing the front and back of the rug are parallel.

4. Drawing a Rug inOne-Point Perspective When the orthogonals are erased the rug is complete. How would you find the center of the rug? Remember how we found the center of the window?

5. Drawing a Wood Floor in One-Point Perspective The seven red points on the line that shows where the floor and back wall meet are equally spaced (use a ruler to do this). This insures that the floor boards will be of equal width

6. Drawing a Wood Floor in One-Point Perspective The orthogonal drawn through the first point shows where the first board is. Think of the vanishing point as the sun and the orthogonals are like the sun's rays.

7. Drawing a Wood Floor in One-Point Perspective The second orthogonal goes through the second point. The wood floor now has two boards. Notice how the boards are wider at the closer end and get narrower as they get nearer to the vanishing point.

8. Drawing a Wood Floor in One-Point Perspective The wood floor is now complete. The boards get wider as they get closer to the viewer and narrower as they get closer to the vanishing point. How would you make a wood floor with boards of unequal width?

9. Drawing a Tile Ceiling inOne-Point Perspective The tile ceiling starts just like the wood floor, with equally spaced points marked off with the help of a ruler. The difference is that the red points are on the line that shows the place where the back wall and ceiling meet.

10. Drawing a Tile Ceiling inOne-Point Perspective Once again, just like the wood floor, orthogonals are drawn from the vanishing point that look like rays from the sun.Theseorthogonals show where the ceiling tiles will be.

11. Drawing a Tile Ceilingin One-Point Perspective The diagonal red line goes across the orthogonals. It starts at one corner of the ceiling and goes to the opposite corner. This line, which will be erased later, will help us draw the tiles. Notice that the parts of the orthogonals that were on the back wall have been erased.

12. Drawing a Tile Ceilingin One-Point Perspective To get the first row of tiles we draw a horizontal line across the top of the ceiling where the red line intersects the red orthogonal. Notice that the diagonal red line intersects all of the orthogonals on the ceiling

13. Drawing a Tile Ceilingin One-Point Perspective The red orthogonal and red diagonal lines intersect (meet) where the next horizontal line is drawn. This line shows another row of tiles. Which row of tiles looks bigger, the first or the second? Why?

14. Drawing a Tile Ceiling in One-Point Perspective The ceiling is completed when the diagonal line is erased. How would you make a tile floor? Could you also draw tiles on the side walls using this method? If you draw the tile ceiling on a paper rotate the paper and see what happens.

15. Drawing a Skylight in One-Point Perspective A skylight is started the same way as a rug is, with a horizontal line showing the side closest to you. Since the skylight is on the ceiling, the horizontal line is drawn on the ceiling.

16. Drawing a Skylight in One-Point Perspective The next step is to draw the two orthogonals that show the left and right sides of the skylight.

17. Drawing a Skylight in One-Point Perspective We now have the front and two sides of the skylight. We need the line that shows the back of the skylight. That line is a horizontal line that is parallel to the line that shows the front of the skylight

18. Drawing a Skylight in One-Point Perspective When the parts of the orthogonals that are not the skylight are erased the drawing looks a little like a rectangular light fixture or even a rug on the ceiling

19. Drawing a Skylight in One-Point Perspective We can make the skylight look more realistic by showing the depth of the ceiling.We do this by drawing two vertical lines of equal height in each of the far corners of the skylight. It almost looks like the start of a step.

20. Drawing a Skylight in One-Point Perspective The next horizontal line completes the inside back wall of the skylight. This line shows the part of the skylight that meets the roof. It is directly above the line that shows the back of the skylight; it is also parallel to it.

21. Drawing a Skylight in One-Point Perspective Once the back of the inside of the skylight is drawn, the inside sides of the skylight can be drawn too. Orthogonals from the two back corners are drawn to show the inside sides of the skylight. This gives the skylight added depth.

22. Drawing a Skylight in One-Point Perspective Notice how the skylight is different from the door, window and rug. It has more depth. You can see the width of the ceiling. Drawing the vertical lines from the back corners of the skylight made a big difference. If you draw the skylight on paper turn the paper upside down. What does it look like? Try turning the paper so that the skyligth is on the side.
